| Research Abstract |
Cabon nanotube(CNT) has high electrical conductivity and mechanical strength. But CNT is hard to disperse into most solvent. Poly(N-isopropyl acrylamide)(PNIPAM) has thermal responsiveness. PNIPAM is hydrophilic at lower temperature, and hydrophobic at high temperature than the lower critical solution temperature(LCST). In this study, PNIPAM was grafted on CNT by grafting from method.CNT was provided with the thermal responsiveness derived from PNIPAM and dispersion state of PNIPAM-grafted CNT was controlled by temperature. In addition, aggregate was formed by iradiating PNIPAM-grafted CNT aqueous dispersion with infrared laser.
